To all whom it may concern:

Be it known that 1, CHARLES E. Loncaan, a citizen. of the United States, residing at East; lVilton, in the county of Franklin and State of Maine, have invented av new and useful Chemical Fire-Extinguisher,of which the following is a specification.

The present invention relates to improve ments in chemical fire extinguishers, the primary object of the present invention being the provision of a novel form of cartridge holding and emptying device adapted to'be reinovably disposed within a tank, the cartridges being filled with acid while the tank contains water and bi-carlwnate of soda, so that when the acid is released to .[low into such water, pressure will he formed in the tank due to the release oi the carbonic acid gas to assist in expellingthe liquid from the tank to extinguish the tire and at the same time produce the gas which in itself a the extinguisher.

i-i. further object of'tho present invention is the provision of a. vial or cartridge hold-- ing device which -arriea a plurality oi such vials or cartridges, the same being provided with a rotary means whereby the various vials or cartridges may be selected and emptied one at a time as is found necessary to extinguish the tire.

With the intriguing and other oh} its in view which will appear as the description proceeds, the invention resides in the combination and arrangement oi parts and in the details oi construction hereina'l'ter dcscrihed and claimed, it lieiugr understood that changes in the precise ein naliaient oi the invention herein disclosed can he made within the scope of what is claimed without departing from the spirit of the invention.

[ designates a tank or reservoir which is disposed in any position in the building and is adapted to contain water in which is .dissolved hit-carbonate of soda, or in fact any chemical that when mixed with an acid will free carbon dioxid gas and at the saine time produce the desired pressure Within the tank ently appear. This tank is provided with an aperture 2 for the removable reception of the sealing cap 3 of the cartridge carrying device, while connected to the sealing cap 8 bv means of the tie rods e and nuts 5 are the lower cartridge or vial supporting plates 6 and 7. By this means the vials or cartridges 8 are detachably supported Within the retainer with their open ends directed downwardl and sealed by the disk 9, composed of a material such as lead thatwill be unaffected bv the acid, within the vials 8, but

which will provide a gasket or cover to prevent the accidental spilling or leaking of the acid from the vials. The disk 9 has formed cmiccutricallv therewith and extending therealn ve the. tube or sleeve 10, which surrounds the eduction pipe or conduit 11 that extends ahovc the supporting cap 3.

Connectml to and carried by the pipe 11 below the container is a bracket 12 which has d sposed upon the upper portion thereof a prong or plli'i'iiifg member l3. This member lit. when the oraeket 12 is raised, as shown in Fin. 3. pierces the disk 9 to release t to contents of a vial S.

The upper end oi the tube or conduit 11 is threadrd or provided with a hose couplingr so that the contents of the tank 1 may he directed through said conduit and to the desired lire lo i A sleeve 1.? is :nljustabl connected upon the conduit 11 above the stuilinrr hox t8 by means ot a screw it), said sleev v being prorided with a handle 1'7, which when in operable relation is adjusted to aline with the racket]? and the piercing member 13. so that when the tuhe ii is rotated manually, it is simply necessary that the handle 17 be disposed above the upper end of one of the :xontainers r vials h to insure of the proper alinoincnt oi? t pi rcing incn ier w th the lillil'tll ol' the t lei; vial.

v.ti n understood lot he present d ice ,l i suunmgr hut. hrietly shite-d .1. i tw l to force the water therefrom, as Will presthat the tank l is filled with or nearly filled with the inixture of Water and preferably .bi-carbonate of soda, and that the container is intl eflposition as shown In Fig 1, and it is desired to'conduct the'liquid of the tank.

dioxid gas contained in the water and bicarbonate of soda .within the tank 1. This action will produce the pressure within the tank land as the lower end of the pipe or conduit 11 is positioned near the bottom of the tank 1, the liquid within the tank, due to the pressure at the freeing of the carbonic acid gas, will be forced through the conduit 11 and out of the eduction end 14 to the'desired, fire location. As soon as the ressure 'has diminished to such an extent t at it is desirable to empty; another vial, the shaft 11 is rotated by the handle 17 as before stated, andjuntil all of the vials 8 are emptied or as many of them as is deemed necessary.

What is claimed is:

1. The combination with a'tank adapted to contain a liquid having mixed therewith a chemical which when acted upon by acid will free a gas, of a sealing container mounted in said tank, and provided with a concentrically disposed eduction conduit mounted for vertical movement within and without the tank, a plurality of chemical retaining cartridges carried by-said container, means for raising and lowering said eduction conduit, and a piercing member carried by said conduit withinthe tank for piercing one car tridge at a time when the conduit is elevated.

2. A chemical container for a fire extinguisher, having a sealing cap, a plurality of cartridges carried by said cap and provided with a puncturable seal, a concentrically disosed eduction conduit rotatably and slidw ly mounted insaid sealing cap, means for rotating and sliding the said eduction conduit, and a seal puncturing member carried by said conduit.
